Due to the alloying elements in the stainless steel, a thin, transparent “passive layer” is formed on the surface. Even if the stainless steel is scratched or damaged otherwise, this passive layer in stantaneously reforms under the influence of oxygen from air or water, thus continuing to protect itself against rust and corrosion.
Ciroldi uses AISI 304 stainless steel in all its products assuring a 100% non-toxic environment with a high level of hygiene.
AISI 304 quality stainless steel is a particular steel alloy that is never tarnished, not even when exposed to air and water, as it has a unique self-protective property which disperses the elements on its surface and prevents oxidising action. This explains why stainless steel always remains shiny and bright even after years of use.
